Serial No. 477,091.

(GRANTED UNDER THE ACT or MARCH 3, 1883, AS AMENDED APRIL so, 1928; 370 o. e. 757

This application is made under the act approved April 30, 1928, and the invention herein described may be manufactured and used by or for the Government for governmental purposes Without payment to me of any royalty thereon.

I hereby dedicate the invention herein described to the free use of the public to take effect upon the granting of a patent to me.

My invention is a cutting tool for use in scarifying trees for the production of naval stores. The tool is radially different from the other tools used for the same purpose.

The angle of the handles of 25 to the vertical plane is one of the important features of my invention. This protects the operator from injury, and also insures proper cutting. Another feature of my invention is the curved steel blade beveled on both sides, as it has been found in scarifying trees for the production of naval stores that a certain cut in the tree to obtain satisfactory results must be made.

By referring to the drawings, Figure 1 is a top or plan view; Figure 2 is a front view, and Figure 3 is an end view.

Similar numerals refer to similar parts throughout the several views.

The tool is described as follows: A curved steel blade 1 beveled on both sides 2, consisting of an are 3 of a circle with a radius of 8 inches with a 4-inch chord is attached to 5- inch iron arms 4. At the end of these arms 4 are metal handles 5 with metal grip, set parallel to each other and at an angle of 25 to the vertical plane.

I claim:

In a hacking tool, a bar, a curved blade portion intermediate the ends of said bar, said bar being bent at right angles at its ends, handles on said bent portion, a plane through said handles and a plane passing through the greatest chord of the blade portion being at substantially 25 to each other.

LENTHALL WYMAN.
